diagnostics Flashcards
What is the animal immunized with to create antibodies
innactivated pathogens
What are monoclonal antibodies used to detect
Pathogens
Antibodies
What are monoclonal antibodies made from
mouse antibody produced by a single clone of b cells
specificity for a single epitope
Direct immunofluorescent antibody test
detection o f pathogen-specific antigens in tissues or blood smears
Diagnosis of infections
Specific for pathogens
What is a disease that direct immunofluorescent antibody test is used for
FeLV
Rabies
Indirect immunofluorescent antibody test
Detection of pathogen-specific antibody
Usually serum
Patient’s IgG
Difference between indirect and direct immunofluorescent antibody test
Direct- Specific antigen
Indirect- Specific antibody
What is a disease indirect immunofluorescent antibody test can be used to detect
ehrlichia canis from ticks
What is ELISA
enzyme-linked immunosorbent assay
what does ELISA test for
test for antigens or antibodies in patient samples
Antigen capture assay
Type of ELISA
Detect pathogens
Antibody capture assay
Type of ELISA used to Detect antibodies
What is in antigen capture ELISA well
Capture Ab to Agent X
Patient serum with agent X
HRP-detection Ab for agent X
HRP substrate
What’s in an anitbody capture ELISA well
Capture Ag
Patient serum with Ab to agent X
HRP-detection Ab
HRP substrate
What’s one problem with antibody ELISA
can’t differentiate between infected and immunized
